jI-Ee it known flmt I, OTTO NZICKER, a citizen 0f the United States 01A1neriea, residing 211;.C11i021g'0, in the eounty 0f Cool: -2u1d State0f I11inois, h:we invented ce1tain newnnd usefu1 Improvemenfs inVe1ocipedes, 0f which the following; is a specifieafion, reference be-Ing Imd 1.herein 10 H10 nfl0ompnnying dmw- 1ngS.

This inven1 ion relates t0 0011 21i11. impr0vements in the construction0L velocipedes; und 1't has f01 its object 110 increase the strength anddumbility m1d a1; fl1e Same time t0 reduee 14110 00st 01 1nm111facture0f fl1e Same; and With these objects in view my invention 0011- sists 0fU10 novel de\i0es':md combinations of devices hereinafter described andspecifieally c1aimed.

In the accompanying h-mvings, Figure 1 represents a side elevation etthevelocipede; Fig. 2, an e1evation of the upper portion 0f theSffllldftl'd ;u1d mach with the hinge parts in position 'f01 conplin'gSame; Fig. 3, a sectional p1an f10m 11110 03 a; in Fig'. l.

Fig. 5is a sectional p1an 0f the upperpart 0'f front standard, showfing thephot-eye; and Fig. G, a p1zm 0f the reach-end pivot. Figs. 7 and 8 Showthe manner 0f connecting the re2u ax1e into the Iower ends 0f ehereaches, m1d Fig. 0 shows a p12u1 0f the saddIe-spring detaehed.

Corresponding letters in the severa] figuves 0f the drawings designateIike parts.

The freut sfanda1d is composed 0f a cast- 1'11g, A, being semi-tubularin section 011 its upper portion 2md having at its uppe1 extremity aforwmdly-c1wved eye int0 which the T-hzmdle Z) is seeured. In the Iowerporti011 0f this ca-sting A is forn1ed a tapering frame, a, against theedges of which are seeured by riveting two sectionally semi-eylindrioalbare, B, tha13 t0 their bottom end s h-ave secured the journal-ca-stingsd for axle e of main wheel O, hzwing treacIIe-cranks f upon itsprojecting ends. This casting A has two marwardly-projectingeye-brackets, g and h, the upper one, g, 0f which has a rearward s1ot,11. The two reach-bars D and D, Wih their forward ends, are rigidlyseeured by riveting against the tw0 sides 0f the re arwardlyextendedwing 0f a casting, E. The front veruical portion 0f this casting E isflattened with a cylindvical trunniondto its upper extremity, m1d Withzu eireular collar t0 its bottom, and a (I0wmmrdly-proj eetingeylindrical t-mnnion, K, b0th trunnions j and k being vertically in 1inewith ea0h 0ther. F01 compling fl1e parts A and E the thin flat portion01'. part E, intermediate 0f trunnions j and k, is inserted in s1ot 5 ofeye-braeket g, while the said trunnions j and k are held in 1ine withthe eyes 0f braekets g 2u1d h, as shown byFig. 2, 2md then par1; E ismoved vertically downwmdfor trunnion K t0 Guter the eye in bmeket h1mtiI its 0011m bears upon such bracket h, when trunnionj ao the Sametin1e will have entered the eye in bracket g. After bein thus connected,a pin, l, is inserted in a sma]l transverse hole 0E trunnion K, justbe1ow braeket h, L'or holding the parts f10111 disconneeting. \Vith thisdevice it Will be seen a streng hinge is produced, which em1 be readilydis'conneeted when desired by simp1y remow ing the pin Z.
